摘　　要：通过试验研究剪切型钢纤维对混凝土的塑性开裂、干燥收缩及混凝土力学性能的影响.试验结果表明,钢纤维对改善混凝土开裂有明显效果,并且还探讨了钢纤维的抗裂、增强机理.The influence of shear-pattern steel fiber on plastic cracking, drying shrinkage and mechanical properties of concrete is studied by experiments. The results show that steel fiber improves obviously concrete cracking and the reinforcing and toughening mechanisms of steel fiber are approached.

关 键 词：剪切型钢纤维 混凝土开裂 收缩裂缝 力学性能
